Robyn Brown wants Kody Brown to be present for all his children.

That’s why the 46-year-old—who shares Dayton, 25, Aurora, 23, Breanna, 21, Solomon, 13, and Ariella, 9, with the Sister Wives patriarch—is trying to bridge the distance between the father of 18 and his kids with former sister wives Meri Brown, Janelle Brown, and Christine Brown.

“I nag him about interacting with his other children,” Robyn said in E! News’ exclusive preview of Sister Wives’ Sept. 28 episode. “He pushes back, tells me to give him space.”

For his part, Kody noted that he would “really love to have a better relationship” with not only the children he shares with his exes but with his former spouses themselves.

“I literally just compartmentalize the heartbreak,” he said. “I would love healing with Meri. I would love healing with Janelle. I would love healing with Christine and, of course, all of my children. But I think we’re in an impasse here because this healing can only happen on their terms.”
